Terminal rule operation device and method

Abstract

A rule operation request associated with a service is received by a terminal. A rule corresponding to the rule operation request is obtained from a rule set associated with the service, where the rule set has been previously obtained from the server based on at least one of a device identifier or a user identifier corresponding to the terminal. A rule tree is generated based on the rule. An operation result of the rule is determined based on the rule tree and service data related to the rule.
